According to a Canadian study published in The Lancet this Friday, August 12, the vaccine against Covid-19 would be “safe” in pregnant women. In France, they have been invited to take their second booster dose since July 20.
Messenger RNA vaccines are good “safe” during pregnancy said a Canadian study published on August 12, 2022 in the international medical journal The Lancet.
During this study, the researchers observed 200,000 vaccinated pregnant women. And seven days after an injection of Pfizer or Moderna, they observed no more miscarriages or stillbirths than in unvaccinated pregnant women. Similarly, sick leaves or medical care were not more numerous than among women of the same age, vaccinated but not pregnant.
It is even strongly recommended that pregnant women get vaccinated. Indeed, in the face of Covid-19, risks during pregnancy are many :
- 22 times more risk of premature birth,
- 8 times more likely to end up in intensive care,
- 5 times more risk of hospitalization of the child in intensive care.
Vaccination and pregnant women: what are the recommendations?
In France, pregnant women can receive Comirnaty mRNA vaccine injections [Pfizer/BioNtech] and Moderna (except for those under 30) from the first trimester of pregnancy. Since July 20, 2022, the Ministry of Health invites pregnant women to receive their 2nd booster dose, also called the fourth dose.
The available studies have not shown any consequences of mRNA vaccines on the course of pregnancy. In contrast, “cases of severe form of Covid-19 in unvaccinated pregnant women have been reported, in France and elsewhere, some leading to stays in critical care, with tracheal intubations and death of the mother during pregnancy“, underlines the EPI-PHARE study.
Pregnant women who have an Ameli account receive a notification in their 4th month of pregnancy encouraging them to vaccinate and, from their 6th month, an e-mail reminding them of the importance of vaccination during pregnancy is also sent to them. sent. In addition, letters will be sent to 21,000 insured persons who do not have an Ameli account, who are between their 4th and 7th month of pregnancy.
Covid-19 vaccine and breastfeeding
On the issue of breastfeeding, the HAS and the Academy of Medicine adopt similar positions, indicating that vaccination in breastfeeding women is possible. The HAS specifies that on the basis of the rapid degradation of messenger RNAs, there is “has no expected effect in infants and children breastfed by a vaccinated woman“. The Academy of Medicine specifies for its part that it is important to preserve breastfeeding by women who have received the vaccine or who have been infected, because of the protective effect of “antibodies transmitted through breast milk“.
